"Those who use tabs and or notation post their songs vs those that don't."

Reading... Non-reading... Tab or notation, has nothing to do with playing ability, but has everything to do with accessibility and efficiency.

For me, it's mere laziness: Ignoring the mechanical aspects of the playing, I can learn a new tune/song from notation in minutes, with minimal effort.
Listening to a cd track will get you there, maybe - in time.
Looking at most tabbed pieces - forget it (unless you already are familiar with the tune or can hear it, and then, again, in time...)

Anything that reduces unnecessary effort and time wasting has to be good.

bf just put his (bad) finger on the problem with tab: Unless you already know exactly how the tune's supposed to sound, in that exact arrangement, it'll be very difficult to figure out from the tab. Little passing "grace notes" look exactly like the main melody notes. There's no indication of rhythm, note duration or dynamics. It also won't help you if you want to play something in a different tuning. But it sure is helpful if you know how something sounds and you're wondering "How in #### did he play that?!" (Which the tab writers often don't know themselves; you get their interpretation of the tune.)
